SPECIFICATION forming part of Letters Patent No. 647,238, dated April 10, 1900.

Application filed September 8, 1829. Serial No. 729,830. (No model.)

of Minneapolis, Hennepin county, Minne sota, have invented certain new and useful Improvements in Computing and Listing Ma chines, of which the following is a specification.

This invention relates to improvements in machines for making computations and for printing the results of such computations upon suitable recording-strips.

The machine, as herein shown, is designed especially for use in banks for printinga list of the checks drawn by each customer,adding the amounts of said checks together, and printing the total amount of such checks.

The invention consists generally in a listing and computing machine provided with a suitable keyboard and computing mechanism, the keys of said keyboard being adapted to be set in positions for operating said computing mechanism, and said keyboard and said computing mechanism being capable of relative movement one past the other for the purpose of. causing the moved or operated keys to engage with and operate said computing mechanism.

The invention consists, further, in novel means for transferring the movements of the primary or listing wheels to the total-result wheels.

The invention consists, further, in novel constructions and combinations hereinafter described, and particularly pointed out in the claims.

The casing.ln the drawings, 2 represents the case of the machine, which may be of any I, provided with the glass panels 5.

suitable or preferred form or construction. I have shown in the drawings a metallic case having a broad substantially-flat base and a box-like inclosure having the forward portion of its top wall inclined. This inclined portion 3 of the top wall forms the support and guide or keyboard for the keys hereinafter referred to. As here shown, the. case is also Those of course may be omitted, if preferred.

The 7teys.Mounted in the inclined wall 3 of the case are the vertieallymovable keys 7, each consisting, preferably, of a flat bar divided or forked at its lower end and provided also near its lower end with a shoulder 9. These keys are provided at their upper ends with the usual buttons or tops provided with suitable figures or characters. The bars Tare of increasing length from the front to the back of the keyboard, so that the lower ends of the keys are in substantially the same plane, and the shoulders 9 are in substantially the same plane. The keys 7 are arranged in rows running from the front to the back of the keyboard and numbered consecutively, as shown in Figs. 1 and 5. I have here shown eight rows of keys, which permit me to register and print numbers up to 99,999,999 or when recording amounts representing United States or Canadian money nine hundred and ninetynine thousand nine hundred and ninety-nine dollars and ninety-nine cents. I do not, how ever, limit myself to any particular number of rows of keys. Each key is provided with a suitable spring 11, preferably having its up per end secured to the key and its lower end free and provided with a projection or raised portion, which holds the key in its elevated position by engagement with the wall of the slot or opening through which the key passes. The keys are by these springs all held normally in an elevated position. lVhen any key is depressed, its spring 11 is compressed, and the key passes to its lower position, as illustrated by the position of one of the keys in Fig. 4E and by the position of one of the keys in Fig. 12.

The mot-able car/'[ug e.-1l1e casing of the machineis provided in the base portion there of with suitable guide-rails 13 and a guideway 13, which extend longitudinally of the machine and preferably nearly its full length. Mounted upon these guide-rails and adapted to slide back and forth thereon is a suitable carriage 15, having preferably, also, the roll 15, that moves in the guideway 13', Fig. 7. This carriage is adapted to be reciprocated in the casing by means of a suitable handle 17, arranged upon a crank-arm 19, that extends through a slot 21 near the bottom of the easing. The carriage 15 has mounted upon it the type-wheels, their supports, and means for operating said wheels, as hereinafter described. In Fig. 3 of the drawings the earriage is shown at the rear end of the casing or in the position that it occupies while the keys are being depressed. in Fig. 4: of the drawings the carriage is shown at the limit of its forward movement, with one of the keys depressed and in position for engagement with the type-wheel-operating mechanism.

The spiral s71 afls.Mou nted in bearings and 21 are the spirally-grooved shafts 23. These shafts extend longitudinally of the machine or in the direction of the movement of the carriage, and there are as many of these spiral shafts as there are rows of keys on the machine. As here shown, the ends of the shafts are provided with journals which are mounted in the hearings or bars Hand 2-1, so as to permit the spiral shafts to turn freely in either direction. The bars 22 and 2% are secured upon suitable standards 27 29 on the forward and rear ends of the carriage. These spiral shafts 2 3 normally remain stationary while the carriage is reciprocated; but when any key of the corresponding row is depressed its forked lower end is brought into position to engage the spiral shaft as the carriage is moved forward, causing the shaft so engaged to be rotated, and the amount of ro tat'ion given to such shaft depends upon the position of the key which engages said shaft. For instance, if a key bearing the figure 9 is depressed it engages the spiral shaft in line therewith almost immediately after the carriage begins its forward movement, and this engagement continues throughout the movement of the carriage, and the spiral shaft is continuously turned until the forward movement of the carriage ceases. It, how ever, the key bearing the figure 1 in any row is depressed, it does not engage the cor responding spiral shaft until the carriage has nearly reached the limit of its forward move ment. Hence the spiral shaft is rotated only during a short portion of the movement of the carriage.

I prefer to provide means for locking each spiral shaft in a stationary position except while it is in engagement with one of the operating-keys. For this purpose I provide in connection with each spiral shaft a lOClili'lgplate 31, mounted upon pivots 32 in the bars 22 and 2% that support the spiral shaft. A spring 33 is provided for each plate 31, and these springs hold the plates against the spiral shafts. Each shaft is also provided with a pin 35, that engages a slot 37 in the plate 31, whereby said shaft is locked except when the plate is held away from the shaft. The operation of this part of the mechanism is clearly illustrated in Fig. 18 of the drawings. Each of the plates 31 is provided at its upper edge with a substantially-horizontal flange 30, having a beveled forward end 3-. lVhen one of the keys 7 is depressed and the carriage is moved forward, the forked end of the key straddles the upwardly-projecting portion of the bar 22, forming the bearing for the corresponding spiral shaft 2 3, and in the further movement of the carriage straddles the spiral shaft. The initial portion of the shaftis made flat, as shown in Fig. 18, and the engagen'ient of the flange of the plate 31 with the outer surface of the keys turns the upper edge of the plate 31 outward away from the spiral shaft, freeing the pin 35 from the. slot 37 before the shaft begins to rotate. The key remains in its depressed position and rotates the spiral shaft during the remaining portion of the forward movement of the carriage and then rotates the shaft in the reverse direction during the reverse movement of the carriage until the end of the shaft passes out of the fork of the key. As soon as this is done the plate 31 is forced by its spring back against the surface of the spiral shaft, and the slot in the plate, engaging the pin on the shaft, locks the shaft and prevents further movement thereof until the plate is again turned away from the shaft by its engagement with one of the keys.

The listing type-wheels and tubular supporting-shafts.Mounted in bearings 39 and 11 on the carriage 15 are the series of tubular shafts 43, arranged one within another, and each provided upon one end with a wormwheel 45, that is engaged by one of the spiral shafts 23, and upon the other end with a typewheel 47. These type-wheels I term the primary or listing type-wheels. These type-wheels may also be termed the temporary or indicating Wheels, as each amount that is to be listed is temporarily indicated or shown on these wheels and is then transferred tothetotal-resultWheels. Thewheels45may be secured by any suitable means upon the tubular shafts. I have here shown each wheel providedwith a threaded split hub 42 and with a clamping-collar 4E4, screwed upon this hub and clamping the hub upon the shaft. (See Figs. 8 and 9.) I do not, however, limit myself to any particular means for securing the wheels to the shafts. Each of the tubular shafts, it will be seen, is mounted in an independent hearing at each end, so that any one of the shafts may turn independently of all the others. Each tubular shaft and type-wheel carried by it rotates at all times with the corresponding spiral shaft 23. Each of the type-wheels is provided upon its circumference with a series of type-figures from 1 to 0, and when in normal position, with the spiral shafts locked against rotation, the type-wheels all stand with the zero-types in line with one another and in printing position. As each spiral shaft is rotated by engagement with one of the keys in the corresponding row the type-wheel upon the corresponding tubular shaft is correspondingly rotated, so as to bring the figure corresponding to that on the depressed key into printing position. When the carriage is reversed, the typeavheels are turned back to zero. If when the carriage is moved forward there are any rows of keys in which no key has been depressed, the spiral shaft in line with that row of keys will remain stationary and zero will be printed by the corresponding type-wheel.

It will be understood that by means of the keys, the spiral shafts, the connected tubular shafts, and the type-wheels carried thereby any desired numbers may be brought into position by turning of the type-wheels to be printed by the means hereinafter described, and that the type-wheels are restored to zero after the printing of each number or amount. By this means, therefore, Where the machine is used for making lists of loankchecks the amounts of the separate checks may be printed.

The totatres'ult typc-w7ieeZs.-It is necessary, in addition, to provide means for adding the several numbers thus printed and printing the total or result of such addition whenever desired. This means I will now proceed to describe, stating first, however, that one of the most important features of my invention consists in the novel and exceedingly simple means that I provide for recording the total result of any number of operations of the machine upon the total-result wheels which may at any time be printed upon the recording-strip, thereby showing the sum of all of the numbers previously printed on the slip. The wheels 49 (which for convenience I call the totalresult wheels) are typewheels similar to the type-wheels 1'7; but they are mounted loosely upon collars 51 on the shaft 53. The collars 51 are secured upon the shaft 53, so as to turn therewith, and each collar has a disk 55, preferably formed integrally therewith and projecting between two of the type-Wheels 49. Each type-wheel 49 has a pin 57 projecting laterally therefrom toward the disk 55, and each disk has a springdog 59 (see Fig. 22) secured to or formed on it, which dog is adapted to engage the pin 57 on the wheel 49. This dog does not prevent the free turning of the wheel in one direction; but if the shaft 53 is turned in one direction each of. the dogs 59 will at some point in the revolution of the shaft come in contact with the pin 57 on the corresponding wheel 49, and said wheel will thereafter turn with said shaft. This means is employed for turning all of the wheels 49 back to zero when it is desired to begin a new set of indicationsand a new computation and new record. The shaft 53 is mounted in standards 6l,which are secured upon a rock-shaft 63, mon nted in suitable bearings 65, forming part of the carriage 15. A bell-crank arm 67 is secured to the shaft 63. (See Figs. 21, 22, 23, and 24:.) Two parallel slots or guideways 69 71 are formed in the base of the machine, and the crank-arm 67 is provided with a springpin 73, adapted to engage either one of the slots 69 or 71. This pin is mounted in a hole in the crankarm, and a spring 75, arranged in the rear of the pin, tends to project said pin into one of said slots. The slots 69 and 71 are connected at their'ends by the cross-slots 68 and 70. (See Figs. 26 and 27.) At one end the slot 71 is provided with the incline 72 and the cross-slot with the inclinej74, and at the e erases other end the slot is provided with the incline 66 and the cross-slot 68 is provided with the incline 64. These inclines are on the illner walls of the slots. The spring-pin 73 normally projects into one of the slots (39 or 71. \Vhen it is in the slot 69, the total-result wheels 49 stand in the position shown in Figs. 23 and 24. "When the pin 73 is in the slot 69, the total-result wheels 49 stand in the position shown in Figs. 21 and 22 and are then in engagement with the transfer-wheels hereinafter described. The slot or guideway 71 extends to the end of the base to permit the pin to travel therein in putting the carriage into or removing it from the casing. hen the carriage 15 is moved forward and the type-wheels 47 are turned to various positions by the moved keys, the pin 73 moves in the slot or guideway 71 and the wheels 49 are, through the transfer-wheels hereinafter described, turned in unison with the wheels 47. When the carriage reaches the limit of its forward movement, the pin 73 has arrived at the end of the slot or guideway 71, has passed over the incline "2 at the end of the guideway 71, and onto the incline 74 in the cross-slot 70. The pressure of the spring 75 on the pin forces the pin to travel down the incline 74, thereby bringing said pin into the end of the crossslot or the beginning of the slot or guideway 69. This movement will turn the crankarm 67 from the position shown in Figs. 21 and 22 to the position shown in Fig. 23 and will carry the total-result wheels 49 out of engagement with the translter-wheels and into engagement with a spring locking-dog 50. It will thus be seen that during the forward movement of the carriage while the listing type-wheels 47 are being turned into position to print upon the recording-slip the amounts indicated by the keys that have been depressed the total-result wheels 49 will move in unison with said type-wheels 47, but that during the backward movement of the carriage when the wheels 47 are turned back to zero the total-result wheels are out of engagement with the type-wheels 47 and do not partake of this reverse or backward movement. Hence the wheels 49 constitute adding or total-result wheels and indicate at any time the total result of any desired number of operations of the machine.

The 25rd;refer-wheels and carrying devfcc. As the type-wheels 47 simply indicate single transactions or single entries made by the machine no carrying device is needed in connection therewith, but the total-result wheels must be provided with a carrying device which will cause each wheel in the series to be turned one step each time that the preceding wheel makes a complete revolution. This result is eifected by the peculiar manner in which I mount and operate the intermediate or transfer wheels.

The transfer-wheels are arranged in engagement with the type-wheels 47, and there are as many of these intermediate or trans fer wheels as there are of the type-wheels 47. Each of the wheels 75 is mounted on a short stub or shaft 77 in a vertically-sliding standard 70. (See Fig. 25.) Each of said standards is provided with a notch or recess 81 and is arranged to. slide vertically between the transverse rod 83, the transverse bar 85, and frames 87. Said rod 83 and said bar 85 are mounted in the vertically projecting frames 87, which form a part of the sliding carriage. The lower ends of the verticallysliding standards 79 are preferably forked, (see Figs. 22, 23, and 24,) and one end of one portion of the fork comes above a transverse rod 80, arranged in slots 91 in depending lugs 93. A pivoted bell-crank lever 95 is arranged in connection with each of the vertically-movingstandards 79. (See Figs. 23 and 24.) These levers extend over the tops of the standards 79, and each lever is provided with a hook 97, adapted to engage the notch 31 :in the standard. A spring is connected to the short arm of each lever and to the stand ard, as shown in Figs. 21, 22, 23, and 2-1.. As the carriage is moved forward the rod 8.) rides over the inclined bars 101. One of said bars 101 is arranged at each end of the rod 39. (See Fig. 7.) As the rod 89 rides over the inclined bars 101 it raises all of the standards 79 that may be in the lower position shown in Fig. 23 to the position shown in Fig. 21, when the hook 07 on the bellcrank lever 05 engages the notch 81 in each stand ard 79 and holds said standard in its elevated position. The transfenwheels 75 are then in the posit-ion shown in Fig. 21, and when the total-result wheels are engaged with the transfer-wheels the motion of the t -'pewheels 47is transmitted through the transfer-wheels to the total-result wheels. if any one of the wheels 47 remains idle during the forward movement of the carriage by reason of the keys controlling said wheel not being depressed, the corresponding transfer-wheel 75 and totalresult wheel 49 will also remain idle, except as hereinafter stated. Each of the wheels 40 is provided at the proper point on its side with a pin 103. I (See Figs. 21 and 22.) This pin is in such position that when the ninetype passes the prii'iting-point this pin comes into engagement with the lever 01' the next succeeding transfer-wheel or the transfer wheel intermeshing with the next succeeding total-result wheel of a higher denomination. The engagement of this pin with thelever disengages the hook 07 from the notch 31, and the standard 79 is depressed or drawn downward by the spring 99 and the transferwheel carried by said standard is moved from the upper position (shown in Figs. 22 ant 2 3) to the lower position. (Shown in the same figures.) As, however, one tooth of this wheel is in mesh at all times with the type wheel 47, which is either stationary or moving in the direction indicated by the arrow in Figs. 21 and 24, the lowering or downward movement of the transferwheel will give ICC to the correspon ding total-result wheel a onestep movement. This operation will take place whether the corresponding wheel 47 is moving or not and whether the transfer-wheel is moving or not, and hence whether the corresponding total-result wheel is being rotated by the type-wheel 4:7 and transfer-wheel or is stationary. hen any one of the wheels 77 has been depressed or lowered in the manner described, it remains in this position, and if the corresponding type-wheel is moving continues to turn and transmit such movement to the total-result wheel until the total-result wheel is disengaged therefrom at the beginning of the backward movement of the carriage. During the return or reverse movement of the carriage any of the standards 79 that have been moved down are elevated by the passage of the rod 89 overthe inclined bars 101, and by engagement of the hooks 97 on the levers 95 with said standards said standards are locked in an elevated position. The bars 101 are each pivoted at one end to the lugs or projections 105, (see Figs. 7, 21,

and 24,) and their opposite ends (which are cut off diagonally on the under side) rest by gravity upon the base of the machine, so that as the carriage is moved backward after each registration and printing operation the rod 89 rides up over the inclined bars 101, as before stated, and raises all of the movable standards 79 that have been released and depressed by the carrying operation of the total-result wheels and causes them to be engaged by the hooks 97 on the bell-crank levers 95, whereby said standards and transfer-wheels are held in this elevated position. Upon the forward movement of the carriage, however, the ends of the rod 89 pass under the raised ends of the bars 101 and lifting the free ends of said bars pass under them also. As the first transfer-wheel in the series never need be moved downward, the first carrying operation being performed by the second transfer wheel, the first transferwheel is mounted on a fixed standard 78, secured upon the first frame 87. (See Fig. 21.) \Vhile there are eight rows of keys, I have shown nine total-result wheels. Of-course any number of such wheels may be used. The .last total-result wheel in the series is not rotated, except that it is moved one step each time the preceding wheel makes a complete revolution, or, in other Words, the preceding wheel carries to this wheel. To produce this carrying operation, it is necessary to provide a corresponding transferwheel and movable standard, and as the opposite tooth of the transfer-wheel must be held when the standard is moved downward, I have shown a ninth type-wheel 47. This wheel, however, does not rotate and need not be provided with type, and instead of being a complete wheel it need only be a portionof a wheel provided with two teeth, with a recess between them to act as a stop for the tooth of the transfer-wheel that prejects into this space. Any suitable means may be provided to hold the movable standards 79 in a vertical position and to guide them while they are being moved. As here shown, I have provided a series of the frames 87, one between every two standards, with the transverse rod 83 and transverse bar passing through all of said frames. The lower end of each standard 79 also passes through a slot in the base of the machine, and these devices serve to hold the standards 79 independently in upright positions and to guide said standards as they are moved. It will be seen that only one spring is used both for the pivoted bellcrank lever and for the movable standard 70. This spring is, as before stated, connected to a hook on the standard and to the short arm of the bell-crank lever. hen the standard is in its elevated position, as shown in Figs. 21 and 24, the spring is distended and is under tension. As soon as the pin on the total-result wheel strikes the lever 95 and throws the hook 97 out of engagement with the notch 81 this spring draws the standard and the transfer-wheel carried by it down ward and gives to the next succeeding'totalresult wheel from that by which the lever was moved a one-step movement. When the standard 79 is raised by the rod 89 riding over the inclined bars 101, the spring 99, acting on the bell-crank lever 95, throws the hook 97 into position to engage with the notch 81, and thereby to lock the standard in its elevated position.

While I have described the transfer-wheels as being given a downward movement for the purpose of carrying from one total-result wheel to another and have shown means for thus moving this wheel vertically, it will be understood that I do not limit myself to this particular way of moving the transfer-wheel for this purpose. It is only necessary to give to each transfer-wheel during the carrying operation a bodily or what I have termed an axial movementthat is to say, the axis of the transfer-wheel is moved down (or it might be moved up) either vertically or in a curved path in the direction of the movement. of the internieshing portion of the total-result wheel and in the opposite direction to the motion of the intermeshing portion of the corresponding temporary or listing wheel.

The printing dem'ce.-The printing device maybe of any suitable or preferred construction. It consists, preferably and generally, of suitable rolls and a spool carrying a strip of paper, a suitably supported and operated inking-ribbon, and means for forcing the paper against the type over the inking-ribbon when it is desired to print any one of the numbers that have been registered on the machine or the total result of any number of such registrations. It will be understeod from the foregoing portion of the description that both the primary or listing type-wheels 47 and the total-result wheels 49 are mounted upon the reciprocating carriage 15 and are therefore moved back and forth with said carriage. The carriage may be stopped, therefore, with either set of wheels in printing position. I have shown in the drawings a simple device for printing from either set of wheels. As here shown, the carriage 15 has mounted at its rear end in the standards 29 a suitable rock-shaft 107, and at one end of said shaft there is secured a double crank 109 111. The crank-arm 19, to which the handle 17 is secured, is connected to the short crank 111, and said crank-arm 19, as before stated, passes through the slot 21 in the casing of the machine. The part of the crank-arm 19 that passes through the slot 21 is broad and flat and slides freely in said slot. The crank-arm 109 is of considerable length and carries at its end the roller 113, which projects into the horizontal groove or way 115. Connected with the groove or way 1.15 are the transverse grooves 117 119, which preferably extend downward from said groove 115. (See Figs. 16,17,and19.) The groove may be formed in the wall of the casing; but I prefer to form this groove in an independent part 11.6, arranged inside of the wall of the casing and suitably supported upon the base of the machine. The short groove 119 is normally closed at the top by a switch 121. (See Fig. 19.) This switch consists of a block having a smooth upper face and secured upon a circular plate 123, that is inserted in the part 116, in which said grooves or guides are located. Arranged at one side of the keyboard is the key 125, that I designate as the total-result key. This key consists of avertically-movable barprovided with suitable means for guiding it and hav ing at its lower end a slot 127, 4, that engages a pin 129, eccentrically placed on the plate 123. A stop 131 is formed upon or secured to a stationary part on the machine under the lower end of the key 125. A spring 133, bearing against the side of the key, tends to hold the lower end directly over the top of the stop 131. This stop when the key is in this position prevents any depression of the key, and thereby prevents an accidental printing from the total-result wheels. lVhen it is desired to print from the total-result wheel, the key is depressed, being first given a slight backward movement at its lower end against the tension of the spring 133 to free it from the stop 131. The key is then depressed and it rotates the plate 123 and turns the switch-block 121 from the posit-ion shown in Figs. 13 and 16 to the position shown in Fig. 17. The switch-block then forms a stop in the groove 115, while leaving the groove 119 open at its upper end. The printing and paper-feed rolls 135 137 are mounted on suitable shafts 136, that are mounted on the arms 139, secured to the diagonally-arranged shaft 111. (See Figs. 5 and 11.) The shaft 1 11 is mounted in suitable bearings 113 on the casing of the machine. The spool of paper 115 is mounted on suitable standards 1 17, and the paper passes under the shaft 1-11 through a slotted guide 1.19, that is secured at one end to the frame 139 and at its opposite end to the cam-hub 183 on the shaft 111. This guide is parallel with the shafts 136. The paper then passes over the roll 135 (speaking of the roll in the position that it occupies in Fig. 1 of the drawings) and then between the rolls and 137. The shaft 141 carries at one end a pinion 153. (See Figs. 2, 5, 7, 9,11, 22, and This pinion is engaged by a vertical ly-sliding rackbar 155, which is held in position by a suitable guide 157. The lower end of the rackbar is provided with an open-ended slot 159. livoted upon the carriage 15 are the two bars 161, preferably suitably connected together and carrying at their free end a plate 163. A crarik-arm 105,secured upon the rockshaft 107, also engages one end of the plate 163. (See Figs. 10 and 11.) During a part of the movement of the carriage the plate 163 is out of engagement with the rack-barg but as the carriage is drawn forward into printing position the plate 163 enters the slot 139 in the lower end of the rack-bar, and this plate is of sufficient length to be in engage ment with said rack-bar when the carriage is in position to bring either set of type-wheels to the printing-point. An inking-ribbon 167, mounted upon suitable spools 171, is brought forward from one spool, is carried around a wire 173 in a slotted aliner-plate, hereinafter described, and carried back to the other spool. The top wall of the casing at this point is provided with an opening 175, through which the paper is brought in contact with the inking-ribbon while it is directly over said type-wheels, and suitable pressure is applied to the paper to cause an impression from the type that are uppermost upon said wheels to be made upon said paper. The paper may be brought in contact with either the primary type'wheels or the totalresult type-wheels. In listing checks, for instance, the amount of each check will be registered upon the primary type-wheels and will then be printed therefrom, and after all of the checks of one customer are thus listed the total amount of said listed checks will be printed from the total-result wheels. To print from the primary type-wheels, the carriage is drawn forward by the handle 17 and crank 19 the full limit of its movement. This movement of the carriage turns the primary typewheels -17 so as to bring under the printingribbon the type on said wheels corresponding to the depressed keys. The end of the crank arm 109 will now be over the slot or guideway 117, and a further movement of the handle 17 in a downward direction will rock the shaft 107, the roll 113 traveling downward in the guideway 117, (see Fig. 16), and through the crank-arm 165 and plate 103, which will now be in engagement with the slot 159 in the rack-bar155, said rack-bar will be moved downward, the shaft 111. will be given a pa r
